  • Front
  • Back
the disease process that occurs following infection with the human immunodeficiency virus
acquired immune deficiency syndrome (AIDS)
a naturally occurring hormone that also may be given as a cardiac drug and has alpha and beta effects, also called epinephrine
adrenaline
a severe reacting to an antigen that occurs after sensitization from prior exposure to the same antigen
anaphylaxis
one of two types of specific immunity that exists in the body, it is primarily mediated by B cells
antibody- mediated (humoral) immunity
a substance foreign to the body
antigen
a large collection of lymph nodes located in the axilla (armpit)
axillary nodes
a white blood cell that may play a role following infection of various areas in the body
basophil
a protein found on the surface of T helper cells that is adversely affected by exposure to HIV
CD4 antigen
one of two types of specific immunity that exists in the body, it is primarily mediated by T cells
cell- mediated immunity
a large collection of lymph nodes located in the neck
cervical nodes
the process of the migration of leukocytes in blood toward areas of bacterial invasion, foreign body or infection
chemotaxis
tissue with no clear boundary that bends with surrounding tissues and contains lymphocytes and other cells
diffuse lymphatic tissue
a normal flora or bacteria found in the gastrointestinal tract that aids in digestion and absorption of food, as well as metabolization of waste products
e coli
a leukocyte that may play a role following infection in various areas in the body
eosinophil
a condition that is potentially fatal to a fetus that occurs during late pregnancy or delivery when a Rh negative mother is exposed to a small amount of Rh positive fetal blood. antibodies to Rh antigens may be produced by mother and enter the fetal circulation and destroy the fetus' red blood cells
erythroblastosis fetalis
a small molecule that will not evoke a specific immune response unless it is combined with other serum proteins, in which case, a severe reaction may occur
hapten
a virus that adversely effects a protein on T helper cells, the CD4 antigen, by causing it to appear as an antigen to healthy cells, resulting in destruction of helper T cells and the inability to fight infections and certain types of tumors
human immunodeficiency virus
the body system that is responsible for providing immunity
immune system
the body's ability to resist damage from foreign substances, microscopic organisms, or harmful chemicals
immunity
a disease that may be transmitted from one person to another via some type of specific organism such as a bacteria or virus
infectious disease
a response of the immune system that results in influx of cells and other chemicals to fight a foreign challenge
inflammatory response
a large collection of lymph nodes located in the groin
inguinal nodes
one of three sets of lymphatic organs that comprise the tonsils, they are located in the posterior margin of the tongue and help protect the body from bacteria introduced into the mouth and nose
lingual tonsils
a thin plasma-like liquid formed from interstitial or extracellular fluid that bathes the tissues of the body
lymph
round or bean shaped structures interspersed along the course of lymph vessels, which filter the lymph and serve as a source of lymphocytes
lymph nodes
tissue that is denser than diffuse lymphatic tissue, found in loose connective tissue of the digestive, respiratory, and urinary systems
lymph nodules
thin-walled vessels through which lymph circulates through the body, they travel close to the major arteries and veins
lymph vessels
inflammation of a lymph node caused by infection
lymphadenitis
any swelling of the lymph nosed, with or without pain
lymphadenopathy
an infection that spreads beyond the local area into the lymphatic vessels causing red streaks to run from the infected area proximally
lymphangitis
vessels of the lymphatic system that cary fluid away from the tissues
lymphatic capillaries
one of the two great lymph vessels, it empties into the subclavian vein
lymphatic duct
a passive circulatory system that transports a plasma-like liquid called lymph, a thin fluid that bathes the tissues of the body
lymphatic system
a type of white blood cell that helps fight infection and provide immunity
lymphocyte
complex proteins produced by T effector cells that recruit mast cells and other nonspecific inflammatory mediators to aid in destruction of antigens
lymphokines
the breakdown of a foreign cell caused, in some cases, when T effector cells bind to the foreign cell
lysis
cells that leave the bloodstream and enter diseased tissues after the neutrophils and are responsible for the later stages of fighting an infection, including the disposal of dead bacteria
macrophages
a large white blood cell that mediates allergic reactions and may play a role following infections of various areas in the body
mast cells
the spreading of a disease from one part of the body to another, especially with many forms of cancer
metastasize
an organism of microscopic size
microorganism
usually the first cells to enter infected tissue, they ingest bacteria through phagocytosis
neutrophils
an immune response that is predictable each time the body is exposed to a particular challenge
nonspecific immunity
bacteria found in certain sites in the body, such as GI tract and oral and nasal cavities, that help maintain homeostasis
normal flora
one of three sets of lymphatic organs that comprise the tonsils. they are located in the back of the throat, on each side of the posterior opening of the oral cavity, and help protect the body from bacteria introduced into the mouth and nose
palatine tonsils
the process of ingesting and destroying foreign matter by certain types of leukocytes
phagocytosis
one of three sets of lymphatic organs that comprise the tonsils, they are located near the internal opening of the nasal cavity and help protect the body from bacteria into the mouth and nose, also called adenoids
pharyngeal tonsils
the immune response to a given substance that is faster and stronger after each subsequent exposure
specific immunity
an organ of the lymphatic system that is located in the left upper quadrant of the abdomen and consists of two types of lymph tissue that are associated with drainage of this organ
spleen
surgical removal of the spleen
splenectomy
the cells that carry out most of the cell mediated immune functions by seeking and destroying foreign materials such as; viruses, fungi, bacteria, and particles
T effector cells
cells that aid the T effector cells in carrying out cell-mediated immune functions
T helper cells
the form into which T cells differentiate when activated by an antigen, the T memory cells remain within the body, ready to respond to a second challenge
T memory cells
cells that suppress the actions of the at effector cells by limiting the specific immune response
T suppressor cells
one of two great lymph vessels, it empties into the superior vena cava
thoracic duct
a triangular shaped gland located below the sternum in the superior mediastinum that produces lymphocytes
thymus
three sets of lymphatic organs, the palatine, pharyngeal, and lingual, that are located in the back of the throat and nasopharynx and protect the body from bacteria introduced into the mouth and nose
